modified forms of clip contacts.

In either form of radio receiver block as shown, in accordance with this invention, it includes a base formed of any suitable insulation material and such base maybe of any desirable contour, but as, shown is squared and provided with rounded corners. Referrin to Figures 1 to 5 of the draw ings, 10 in icates the base, having' its lower face formed with a circular recessor pocket 11 of substantial depth and extending through the base 10, near each corner thereof s a hold-fast device 12, for fixedly securing the base 10 to a suitable sup rt; Arranged against the lower'face of the biise 10 is a plate 13 of any suitable material,

which is employed for closing the rem or.

)ocket 11 and which'is secured in position ythe hold-fast devices 12.

Connected to and projecting upwardly from the base 10, is a pair of primary terminals, as indicated at 14,15 and each' of which is in the form of a binding post coinprising a body portion 16, formed with a transverse opening 17, a verticall dis osed opening 18 which communicated wit the opening 17 and has a threaded wall for engagement by the threaded shank19, of a emdm screw 20. The body portion 16 is form with a socket 21 havin athreaded wall which is engaged by t e threaded shank 22 of a binding screw 23 carrying a air of disks 24, 25. i

The binding screws 20 of the terminals 14, 15, are em log'ed for detachably connecting respective y to the terminals 14, 15, circuitconductors 26, 27, which lead to a radio receiving set, not shown.

i The radio tele hone receiver block, is

shown, by way 0 example, for use in connection with six telephone receivers but this number can be increased or diminished if desired, and the drawing illustrates. two .roceivers connected with the base 10. The

receivers are indicated at 28, 29 and each includes a pair of circuit wire connections 30, 31 formed at the free end with a circuit closing tip 32.

Associated with the telephone receivers, is a series of secondary terminals, two of which are indicated at 33 and the others at 34. The secondary terminals 33 are con- 1' st cted in the same manner as the termin s 14 or 15 and are clearly shown in Fig ure 5. Each of the secondary terminals 34 is in the form of a binding post and comprises a body portion 35 provided with a pair of transverselyhextending superposed openings 36, 37. e body portion 35 is f rthermore provided with. an opening 38 isposed at right angles with respect to and communicating with the opening 37. The wall of the opening 38 is threaded and with which engages the threaded stem 39 of a binding screw 40. The body portion 35 at its upper end is formed with a vertically isfiosed opening '41 which communicates wit the opening 36 and hasathreaded wall, and en ging with the said wall is the threaded stem 42 of a binding screw 43. The body portion '35 is furthermore provided at its lowerend with a socket 44, having the wall thereof threaded and engaging with said wall is a threaded stem 45 of av binding screw 46. Carried by the binding screw 46 is a pair of disks 47, 48. Each of the secondary terminals 34, as stated, is provided with the pair of bind ing screws 40, 43 and which are employed for connectin a pair of contact tips 32 of a pair of telep one receivers with a terminal 34, as shown in Figures 1 and 4. The terminals 33 of the secondary terminal are employed for connecting but one telephone receiver tip 32 therewith, and the binding screw for such purpose is indicated at 49 and the other binding screw of each terminal 33 is indicated at 50.

The bindin screws 46 of the terminals 34 are not on y em loyed for securing circuit connections wit 1 said terminals, but are further employed for fixedly securing the terminals 34 to the base 10, and for such purpose the screws 46 extend up through openings 51 formed inthe base and engage-in the bed portions 35. The bind ing screw 0 each terminal 33 of the secondary terminals is employed for the same (purpose as the binding screw 46 and exten 5 up through an o enmg-51.

The base 10 has seen therewith a series of contacts 52 and the said contacts associate withthe terminals 34 and one of the terminals 33. Each of .the contacts 52 includes a head formed with a shank 53 which extends through the opening 54 formed in the base 10 and has a threaded lower portion 55 carrying a pair of securing nuts 56. The contacts 52 are spaced from the terminals 34 and that lel'llllllill 33 0f the secondary terminals, and extending from the shank 53 of each contact to a binding screw 46 of each terminal 34 and to the binding screw 50 of the terminal 33 is a circuit connection 57. The other terminal 33 of the secondary terminals is connected to the terminal 14 by a circuit connection 58.

Rotatably mounted in the base 10, centrally thereof, is a vertically disposed shaft 59, provided at its upper end with a cap member of insulation. The shaft 59 extends into the recess 11 and has connected therewith by the securin device 61, a circuit connection 62, whic is connected to the lower end of the terminal 15. Secured to the shaft 59 so that it will be carried therewith, when the shaft 59 is shifted, is a circuit openin and closing member 63, having a depen ing outer end 64, for enement with the contacts 52.

e member 63 is employed for selectively engaging with the contacts 52 for the purpose of closing the circuit to the receivers.

In Figure 1 of the drawings the c0ntacts are indicated at A, B, C, D, E and F, for the purpose of clearly setting forth the closing of the circuits with respect to the telephone receive-rs. It will be assumed that the member 63 has been shifted to engagement with the contact A which would close the circuit to the receiver 29, through conductor 27, circuit connection 62, shaft 59, member 63, contact A, circuit connection 57, the secondary terminal connected with the contact A, receiver 29, secondary 7 terminal arranged opposite the terminal 14,

circuit connection 58 and conductor 26.

Contact F, then all the receiveis would be in circuit. The receivers are employed for bridgin the circuit between the secondary termina 8. Y

Referring to Figures 6 and 7 of the drawings, the base is indicated at 65 and the re cess or pocket in its lower face at 66. Connected to the base 65 is a pair of primary terminals 67, 68, to which are secured respectively the conductors 69, 70, which are in circuit with theradio'receiving set. Secured to the base 65 is a series of secondary terminals 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81 and 82. Secured to the base 65 is a series of contacts 83, 84, 85, 86, 87 and 88. Rotatably connected to the base, centrally thereof, is a shaft 89 provided with a circuit opening and closing member 90.

Each of the terminals 67, 6s and 71 a; 82',

as a secondary 'terminal33 hereinbefore re-. ferred to. Each of the contacts 83 to 88 is constructed in the same manner as the contacts 52 hereinbefore'referred to. The shaft- 89'and circuit opening and. closing member is set u and constructed in; the same manner as t ie shaft 69 and the member 63 hereinbefore referred to; Leading from the -ter-}' minal 68 shaft 89 is a circuit connection 91. Leading from the terminal Gite-the terminal 71 is a circuit connection-92. Leadin from the contact 83 to 'thet'erminals 72 an i i 73 are circuit connections 93. Leading fifom' the contact 84 to the terminals-7" and 75 are,

circuit connections 94.= Leading'from the contact 85 to the terminals 76 and 77 are the circuit connections" 95. Leadin 1 from the contact 86 to the terminals 78131 1 79 are circuit connections 96, Leading. froin the contact 87 tothe terminals 80 and 81 are the circuit connections '97; Leading from the contact 88 to the terminal 82 is the circuit'connection 98.

In the form shown in Figu jm 'l a'pai'r of- Secondary terminals is employed for connecting a telephone-receiferjil? or 100 with the base.

If the membi 90'ls -to;cn'gage'the contact 83, the circuit to the .recciyerfli) will' be closed, as is obvious,- and-iii shifted'to engage the other contacts,- diclditionalv receiver circuits will lie/closed as is obvious.

In lieu of setting up thesecOndary' terminals in themannerns shown 1nconnection with either one of the foims, clamping clips of the'singletype as shown in Figure 8 and indicated at" 101 can -be cm'plozedjn the form shownin Figurcs ti and l and clamping clips of the duplex type, as indicarted at- 102, intljigure 9 can be Shown in connection with the form shown in Figures 1 and 2. The clips illustrated in F1gurcs'8 :and'9 are ofi known construction and it is inclusive, is constructed in the same manner thought-unnecessary to describe the same.

From the foregoing construction of radio telephone receiver block a device is set up whereby telephone receivers can be 5m cessively cut in with a radio receiving set,

already cut in, and which operation is had withoutan inconvenience whatsoever, and

although he preferred embodiment of a f radio tele honerecciver block in accordance it is to be understood that changes in,the details of construction can be had which fall within the lightpf the invention as claimed. lVhat I claim is A radio telephone receiver block comin' fromieach' of said contacts to each of said terminals, means for securing said conductors'tosuid terminals and further for securing the terminals to the base, circuit forming ci'innectiunssecured to said pair of 'terminals and adapted to lead to a radio re ccivingset, acircuit conductor leading fromone of the terminals of said pair to one of the terminals of said series, a shiftable. circuit opening and closing member v With'this'invention is as described and illus- .trated, yet
